Abstract

A plastic silencer (12) surrounds a compressed air tool (11) and forms an exhaust chamber (27) around the tool. Two exhaust tubes (31, 32) from the chamber (27) are to the greater part situated in the chamber. A number of holes (35, 36) have been drilled near the inlet ends of the tubes. As a result the building up of ice in the inlet is prevented.
